The Yamaha YM2151, also known as OPM (FM Operator Type-M) is an eight-channel, four-operator sound chip developed by Yamaha.It was Yamaha's first single-chip FM synthesis implementation, being created originally for some of the Yamaha DX series of keyboards (DX21, DX27, and DX100 [1]).
The YM2203, a.k.a. OPN (FM Operator Type-N), is a six-channel (3 FM and 3 SSG) sound chip developed by Yamaha.It was the progenitor of Yamaha's OPN family of FM synthesis chips used in many video game and computer systems throughout the 1980s and early 1990s.
Doug Neubauer is an American integrated circuit designer, video game designer, and programmer.Following graduation for Oregon State University and working at National Semiconductor, Neubauer worked at Atari, Inc. where he would develop the logic design on Atari's POKEY chip and designing and programming the video game Star Raiders (1980) both for the Atari 8-bit computer line.
Some critics believe that a good tutorial should necessarily allow the player to discover game mechanics for themselves without being told how to do them, as is the case with the original Metroid, [16] as well as Minecraft, [17] although the latter does have a set of tutorial worlds available on the Legacy Console Edition, varying based on the game version, that provide a more traditional ...
Simple relaxation oscillator made by feeding back an inverting Schmitt trigger's output voltage through a RC network to its input.. An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave, [1] [2] [3] powered by a direct current (DC) source.
A numerically controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e., clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal. [1] NCOs are often used in conjunction with a digital-to-analog converter (DAC) at the output to create a direct digital synthesizer (DDS). [3]
AY-3-8500 chip. The AY-3-8500 "Ball & Paddle" integrated circuit was the first in a series of ICs from General Instrument designed for the consumer video game market. These chips were designed to output video to an RF modulator, which would then display the game on a domestic television set.
VCOs can be generally categorized into two groups based on the type of waveform produced. [4]Linear or harmonic oscillators generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a resonator with an amplifier that replaces the resonator losses (to prevent the amplitude from decaying) and isolates the resonator from the output (so the load does not affect the ...
